Description

The TS4890 is an audio power amplifier, which

can deliver 1 W of continuous RMS output power

into 8 W load @ 5 V.

This audio amplifier shows 0.1% distortion level

(THD) from a 5 V supply for a Pout = 250 mW

RMS. An external standby mode control reduces

the supply current to less than 10 nA. An internal

thermal shutdown protection is also provided.

The TS4890 has been designed for high quality

audio applications such as mobile phones, and to

minimize the number of external components.

The unity-gain stable amplifier can be configured

by external gain setting resistors.
